AUTOMATIC PLATE VALVE.

Specification of Letters Patent. Patented Apr, 18, 1922.

Application filed December 26, 1914, Serial No. 879,117. Renewed July 25, 1918. Serial No. 246,781.

To all whom it may concern Be it known that 1, MICHAEL RIESNER, a citizen of the United States, residing at Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Automatic Plate Valves, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to automatic plate valves of that class in which the valve consists of a thin elastic plate, the special object of the invention being to provide an improved valve of this class, in which the valve shall be properly held in position and guided in its opening and closing movements, without any recesses for the valve on the valve seat, thus permitting the valve seat to be formed and finished as a plain surface.

For a full understanding, of the invention a detailed description of constructions embodying the invention in preferred forms will now be given in connection with the accompanying drawings, forming a part of this specification, and the features forming the invention then specifically pointed out in the claims.

In the drawings:

Figure 1 is a central section of a valve construction, embodying the invention in one of its preferred forms.

Figure 2 is a section on the line 2-2 of Figure 1.

Figure 3 is a plan View with the cappartly broken away.

Figure 4 is a view similar to Figure 1, with the valves opened.

Figures 5 and 6 are similar to Figures 1 and '3, showing a modification with stops for the opposite ends of the valves.

Figures 7 and 8 are similar views, showing a modification with stops that act also to hold the valve in position sidewise.

. Figures 9 and 10 are similar views, showing the valves held in position sidewise by the cap bolts.

Figures 11 and 12 are similar views, showing a modification, in which the valve cap forms end stops for thevalves and acts also to hold the valves in position sidewise.

Referring to the drawings, and especially to the construction contained in Figures 1 to 4: A is the valve seat, shown as of circular form and having the series ofstraight ports a, each of which is controlled by the plate valve B, which opens against the cap or abutment C.

Valves B are held in position and guided without recesses or projections on .the valve seat A, the latter thus being formed and finished as a plain surface co-acting With the valves in their closed position. The valves are held in position sidewise and guided in their opening and ctosing movements as:

follows: Recesses 1 in the cap receive the ends of the valves, these recesses having in clined or curved Walls on the side toward which the valves open, so as to permit the latter to bend freely in the opening movement, and the side walls 2 of the recesses act to hold the valves in position sidewise in line with the ports a. The cap C preferably is provided also with intermediate guides 3, shown as arranged at the middle and on opposite sides of the valves, Which aid in holding the valves in proper position and guiding them in their opening and closing movements; these guides extending from the cap C to the valve seat A.

The abutment surface of the cap is shown as formed so as to reduce the amount of finishing required, the open. valve bearing against it only over a portion of its surface, but it will be understood that this is not essential, and used only for convenience of manufacture.

The operation of the construction will be clear from the drawings without extended description, it being understood that the valves B lie fiat upon the valve seat A above the ports a in normal position, as shown in Figures 1 to 3, and bend upward in opening to the position shown in Figure 4, their opening movement being limited by the abutment surface of cap C, and that the valves are held in position and guided in their opening and closing movements by the walls of the recesses 1 and the intermediate guides 3.

The construction shown in Figures 5 and 6 is similar to that shown in Figures 1 and 4 above, except that the valve seat I) and cap E- are shown as rectangular, the intermediate guides 3 are omitted, and separate stop bars 4 are set into the cap- E at the' opposite ends of the valves B, to form stops for the valves against longitudinal movement, while leaving them free for vertical bending. 1

Figures 7 and 8 show the same construction as Figures 5 and 6, except that stops are used which act also to position the valve sidewise, so that the recesses 1 in the caps of Figures 16 are not required, but the cap may be formed with a uniform curved lower surface. In this construction the valves B are shown as provided with notches 5 at their ends, which receive pins 6 secured in the valve seat and cap, so that the valves are held in position by the pins both longitudinally and sidewise.

Figures 9 and 10 show the same construction as Figures 7 and 8, except that the valves are held in position sidewise and guided by having their ends entered between bolts 7, by which the cap is secured to the valve seat. The valves may be guided similarly by pins inserted in any manner.

Figures 11 and 12 show a construction in which the valve seat D has a cap F provided with guiding slots 8, and the valves B are provided with portions 9 reduced in width at their ends and entering the slots 8, so that the walls of slots 8 co-act with the reduced portions 9 to hold the valves B in position sidewise, and the shoulders formed by the reduced portions abut against the cap to form longitudinal stops for the valves.

It will be understood that the invention may be embodied in other constructions than those shown, many modifications being possible without departing from the invention as defined by the claims.

What I claim is:

1. The combination of a valve seat having one or more ports, oneor more thin elastic plates forming a valve or valves and having both ends free to permit uniform bending of the valve or valves in opening, and a cap or abutment limiting the opening movement of the valve or valves and provided with means at opposite ends of the valve or valves above the valve seat for holding the valve or valves in position sidewise and permitting the bending movement without recesses in the valve seat, and additional side guide; for the valve or valves on the capor abutment between the ends of the valve or valves.

2. The combination of a valve seat having one or more ports, one or more thin elastic plates forming a valve or valves and having both ends free to permit uniform bending of the valve or valves in opening, a cap or abutment limiting the opening movement of the valve 01' valves and provided with means at opposite ends of the valve or valves above the valve seat for holding the valve 01' valves in position sidewise and permitting the bending movement without recesses in the valve seat, and stops at the end of the valve or valves limiting their longitudinal movement.

A check-valve comprising a two-part casing, one part having inlet passages separated by a partition, the other part having .outlet passages and a central partition arranged at right angles to the partition of the first named part, recessesv transversely arranged 1n the inner faces of the partitlon and lateral portions of the second named ported in the other member to move bodily toward and away from the inlet passages, the said member being provided with suitable outlet passages.

5. A check valve composed of a casing consisting of two members. one member having a plurality "of inlet passages separated by spacing partitions, the other member having outlet passages; dividing partitions between said passages, said member and partitions having suitable recesses formed therein and a plurality of relatively thin valve pieces mounted in said recesses to move toward and away from the exit extremities of the inlet passages.

6. A check valve composed of a casing consisting of two members, one member having a plurality of inlet passages separated by spacing partitions, the other memher having outlet passages, a central partition between said outlet passages disposed at right angles to the spacing partitions between the inlet passages of the first named member and a plurality of thin valve pieces mounted between said members to move toward and away from the exit extremities of the inlet passages.

7. The combination of a valve seat having one or more ports. one or more thin plates forming a valve or valves adapted to cover said ports, and a cap or abutment limiting the opening movement of the valve or valves, means at opposite ends of the valve or valves above the valve seat for holding the valve or valves in position sidewise, and additional side guides for the valve or valves on the cap or abutment between the ends of the valve or valves.

8. The combination of a valve seat having one or more ports, one or more thin plates forming a valve or valves adapted to cover said ports, and a cap or abutment limiting the opening movement of the valve or valves, means at opposite ends of the valve or valves above the valve seat for holding the valve or valves in position, additional my hand, in the presence of two subscribing side guides for the valve or valves on the witnesses. cap or abutment between the ends of the valve or valves, and stops at the end of the MICHAEL RIESNER' 5 valve or valves limiting their longitudinal Witnesses:
